Pacific typhoon seasons
1988, 1989, 1990, 1991, 1992

The 1990 Pacific typhoon season has no official bounds; it ran year-round in 1990, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November.[1] These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1990 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.

[edit] Storms

31 tropical cyclones formed this year in the Western Pacific, of which 30 became tropical storms. 21 storms reached typhoon intensity, of which 4 reached super typhoon strength.

[edit] Severe Tropical Storm Koryn

Severe tropical storm (JMA)
Category 1 typhoon (SSHS)
Duration January 8 – January 17
Intensity 100 km/h (65 mph) (10-min),  980 mbar (hPa)

On January 12, both the JMA and the JTWC identified a tropical depression in the northwest Pacific Ocean. The depression intensified over the period of a day to become a tropical storm on January 13, when it received the name Koryn from the JTWC. According to them, but not the JMA, Koryn reached hurricane-equivalent strength on January 15, when it peaked in intensity. The storm then weakened quite rapidly until it became extratropical on January 17, at 1800 UTC.

[edit] Tropical Storm Lewis

Tropical storm (JMA)
Tropical storm (SSHS)
Duration April 29 – May 3
Intensity 65 km/h (40 mph) (10-min),  998 mbar (hPa)

Tropical Storm Lewis was a minimal tropical storm that only held said intensity for two days.

Intensity 100 km/h (65 mph) (10-min),  980 mbar (hPa)

A tropical disturbance trekked across the Philippines in mid June, upon entering the South China Sea a depression formed. The depression was upgraded to Tropical Storm Nathan on June 16. Tropical Storm Nathan reached peak intensity of 65 mph (100 km/h) shortly before striking Hainan Island. In the South China Sea the Chinese ship Tien Fu sank killing 4 people. In southern China torrential rains caused flooding in Guangdong and Zhanjian Provinces killing 10 people, two people drowned in Macau due to high waves. Tropical Storm Nathan then continued northwestwards making a final landfall near the Vietnam/China border.[2]

The monsoon trough spawned a tropical depression east of the Philippines on June 15. It tracked to the northwest then westward, slowly organizing into a tropical storm on June 18. Ofelia turned more to the northwest and became a typhoon on June 20. Paralleling the east coast of the Philippines, it reached a peak of 100 mph (155 km/h) winds before hitting Taiwan on June 23. Ofelia weakened over the country, and brushed eastern China before dissipating on June 25 near Korea. Ofelia caused heavy flooding throughout its track, resulting in at least 64 casualties.

Typhoon Percy, which developed on June 20, reached a peak of 135 mph winds while located a short distance east of the northern Philippines. Increasing vertical shear weakened Percy to a 95 mph typhoon before crossing extreme northern Luzon on the 27th, an area that felt the effects of Ofelia only days before. It remained a weak typhoon until hitting southeastern China on the 29th before dissipating on the 1st. Percy caused serious damage and flooding in the Carolina Islands and northern Philippines, amounting to 9 deaths.

Tropical Storm Gene was named as the storm moved towards the northwest and strengthened into a typhoon the next day. Typhoon Gene reached peak intensity of 95 mph on the 27th shortly before recurving towards the northeast. Gene then skimmed the coasts of Kyūshū, Shikoku and Honshū Islands in Japan before moving out to sea and turning extratropical.

[edit] 1990 storm names

Western North Pacific tropical cyclones were named by the Joint Typhoon Warning Center. The first storm of 1990 was named Koryn and the final one was named Russ. The name Mike was retired after this season, and was replaced by Manny, as evidenced in the 1993 Pacific typhoon season.

[edit] Philippines

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) uses its own naming scheme for tropical cyclones within its area of responsibility. Lists are recycled every four years. This is the same list used for the 1986 season. The name Ruping was retired after this year and was replaced by Ritang.
